There's no easy way to clear a path through a minefield. Options range from tracked vehicles pummeling the ground with whirling flails to individual soldiers gingerly poking the ground and then defusing mines one by one. The Defense Department, cognizant of the need for both speed and safety in beach landings and other operations, is looking at another alternative--masses of small darts raining down on suspect terrain.
A new imaging system promises to pinpoint the location of a weapon concealed on a person without using a metal detector, a pat-down or the slightest dose of radiation, all thanks to some heavenly technology.
The BIS-WDS Prime combines "millimeter wave sensor" technology, video cameras and algorithm software to detect "objects made of metal, plastic, ceramic and composite hidden beneath a subject's clothing" from up to 45 feet away, according to manufacturer Brijot Imaging Systems. The subject doesn't have to stand still or even know he's being scanned.
The technology, which is used … Read more
Toy guns have come a long way from the days of Nerf. This one, the Airsoft Submachine Gun featured on ThinkGeek, is about as far from those neon-green pistols as they get. It has freaking LASER SIGHT. And an illuminator flashlight built in. And it's so awesome, it comes with protective goggles. Not to mention the fact that it actually looks like a legitimate weapon, rather than something out of "The Jetsons."
Microwave ovens have been used to heat corn dogs melt toys. Now, two inventors want to employ them to liquidate an enemy in battle.
In an application with the U.S. Patent and Trademark Office, two inventors say they have come up with a way to get the magnetrons, the device inside microwave ovens that turns electrical energy into microwaves, to essentially synchronize.
Right now, the largest magnetrons can crank out about 1 megawatt. That's a lot of power, but the device is expensive and delicate. By getting off-the-shelf magnetrons to lock into the same frequency and phase, you … Read more
